A micro motor is fixedly mounted on the inner wall of the drive box, and a drive wheel is fixedly mounted on the output end of the micro motor. This invention, through the frames fixed on both sides of the outer surface of the connector body, stably supports the motor operation. When the motor drives the threaded rod to rotate, it can precisely move the threaded sleeve along the threaded rod, thereby adjusting the position of the drive box via the bracket. This ensures that the subsequent protective plate accurately covers the critical interface area of ​​the connector body, effectively preventing external moisture intrusion and solving the problem of insufficient waterproof performance of traditional Type-C connectors.

Description

Technical Field

[0001] This utility model relates to the field of Type-C connector technology, specifically a Type-C connector with waterproof performance. Background Technology

[0002] Connectors, also known as plugs or sockets, are generally electrical connectors. They are devices that connect two active components, transmitting current or signals. The male and female terminals, upon contact, can transmit information or current. The basic performance characteristics of connectors can be divided into three categories: mechanical performance, electrical performance, and environmental performance. Another important mechanical performance characteristic is the mechanical life of the connector. Mechanical life is essentially a durability indicator, referred to as mechanical operation in the national standard GB5095. However, existing connectors lack the ability to seal and waterproof the connector head, making them susceptible to water corrosion. Under prolonged contact with moisture, ordinary plastics will swell and deform, leading to a decline in their mechanical properties and an inability to effectively protect the internal electrical components. Furthermore, ordinary plastics are not very corrosion-resistant; in humid environments containing corrosive gases or liquids, they are easily corroded, further reducing the connector's lifespan. Utility Model Content

[0003] The purpose of this invention is to provide a waterproof Type-C connector with the advantages of being sealed and waterproof.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a waterproof Type-C connector, comprising a connector body, frames fixedly mounted on both sides of the outer surface of the connector body, a motor fixedly mounted on one side of the frame, a threaded rod fixedly mounted on the output end of the motor, a threaded sleeve threadedly mounted on the front surface of the threaded rod, a drive box fixedly mounted on the top of the threaded sleeve via a bracket, a micro motor fixedly mounted on the inner wall of the drive box, a drive wheel fixedly mounted on the output end of the micro motor, a belt drivingly connected to the front surface of the drive wheel, a driven wheel drivingly connected to the top of the belt, an output shaft fixedly mounted on the inner surface of the driven wheel, and a protective plate fixedly mounted on one end of the output shaft that is close to the other.

[0005] As a preferred embodiment, a connecting wire is fixedly installed at the right end of the connector body, and a connector head is fixedly installed at the left end of the connector body.

[0006] As a preferred embodiment, a guide rail is fixedly installed on the inner wall of the frame, and the inner cavity of the guide rail is fixedly installed on one side of the threaded sleeve by a guide rod.

[0007] As a preferred embodiment, the connector body includes a polyurethane coating layer, and the bottom of the polyurethane coating layer is coated with an epoxy furan coating layer.

[0008] As a preferred embodiment, the bottom of the epoxy furan coating layer is coated with a water-based inorganic zinc-rich coating layer, and the bottom of the water-based inorganic zinc-rich coating layer is coated with a Teflon coating layer.

[0009] As a preferred embodiment, the thickness of the polyurethane coating layer is 0.03 mm, and the thickness of the epoxy furan coating layer is 0.02 mm.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention utilizes frames fixed to both sides of the connector body's outer surface to stably support motor operation. When the motor drives the threaded rod to rotate, it can precisely move the threaded sleeve along the threaded rod, thereby adjusting the position of the drive box via the bracket. This ensures that the subsequent protective plate accurately covers the critical interface area of ​​the connector body, effectively preventing external moisture intrusion and solving the problem of insufficient waterproof performance of traditional Type-C connectors. It improves the safety of connectors in humid and water-related scenarios. After the micro motor fixed to the inner wall of the drive box starts, its output end's drive wheel can drive the driven wheel to rotate via a belt, thereby causing the output shaft to drive the protective plate to rotate. This transmission structure can flexibly adjust the opening angle and coverage area of ​​the protective plate. It can completely close the protective plate to achieve full waterproofing when the connector is idle, and quickly open the protective plate when the connector needs to be plugged in or unplugged without affecting normal use. It is suitable for various scenarios such as daily plugging and unplugging and temporary outdoor use. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example 1:

[0015] Please see Figures 1-2 As shown, this utility model provides a waterproof Type-C connector, including a connector body 1. Frames 6 are fixedly installed on both sides of the outer surface of the connector body 1. A motor 3 is fixedly installed on one side of the frame 6. A threaded rod 5 is fixedly installed at the output end of the motor 3. A threaded sleeve 4 is threadedly installed on the front surface of the threaded rod 5. A drive box 8 is fixedly installed on the top of the threaded sleeve 4 via a bracket. A micro motor 11 is fixedly installed on the inner wall of the drive box 8. A drive wheel 12 is fixedly installed at the output end of the micro motor 11. A belt 13 is drivenly connected to the front surface of the drive wheel 12. A driven wheel 14 is drivenly connected to the top of the belt 13. An output shaft 10 is fixedly installed on the inner surface of the driven wheel 14. A protective plate 9 is fixedly installed at one end of the output shaft 10 that is close to the other.

[0016] This technical solution uses frames 6 fixed on both sides of the outer surface of the connector body 1 to stably support the operation of the motor 3. When the motor 3 drives the threaded rod 5 to rotate, it can drive the threaded sleeve 4 to move precisely along the threaded rod 5. Then, through the bracket, the drive box 8 is adjusted to ensure that the subsequent protective plate 9 can accurately cover the key interface area of ​​the connector body 1, effectively blocking the intrusion of external moisture, solving the problem of insufficient waterproof performance of traditional Type-C connectors, and improving the safety of the connector in humid and water-related scenarios. After the micro motor 11 fixed on the inner wall of the drive box 8 is started, the active wheel 12 at its output end can drive the driven wheel 14 to rotate through the belt 13, thereby causing the output shaft 10 to drive the protective plate 9 to rotate. This transmission structure can flexibly adjust the opening angle and coverage of the protective plate 9. It can completely close the protective plate 9 to achieve full waterproofing when the connector is idle, and can quickly open the protective plate 9 when the connector needs to be plugged in or unplugged without affecting normal use. It is suitable for various scenarios such as daily plugging and unplugging and temporary outdoor use. Example 2:

[0017] Based on Embodiment 1, this utility model is as follows: Figure 1 and Figure 3 As shown, a connecting wire 2 is fixedly installed on the right end of the connector body 1, a connector head 7 is fixedly installed on the left end of the connector body 1, a guide rail is fixedly installed on the inner wall of the frame 6, and the inner cavity of the guide rail is fixedly installed on one side of the threaded sleeve 4 through a guide rod. The connector body 1 includes a polyurethane coating layer 101, an epoxy furan coating layer 102 is coated on the bottom of the polyurethane coating layer 101, a water-based inorganic zinc-rich coating layer 103 is coated on the bottom of the epoxy furan coating layer 102, and a Teflon coating layer 104 is coated on the bottom of the water-based inorganic zinc-rich coating layer 103. The thickness of the polyurethane coating layer 101 is 0.03 mm, and the thickness of the epoxy furan coating layer 102 is 0.02 mm.

[0018] By adopting the above technical solution, the guide rail and guide rod are used to limit the threaded sleeve 4. The polyurethane coating layer 101 has the advantages of strong adhesion, good wear resistance, high hardness, and good chemical and weather resistance. The epoxy furan coating layer 102 has outstanding corrosion resistance, heat resistance and wear resistance, and can also improve the smoothness. The water-based inorganic zinc-rich coating layer 103 has the advantages of excellent adhesion, wear resistance, heat resistance, radiation resistance and solvent resistance.

[0019] The working principle of this utility model is as follows: the output end of the motor 3 drives the threaded rod 5 to rotate clockwise. Since the threaded sleeve 4 and the threaded rod 5 are threadedly connected, the threaded sleeve 4 moves along the threaded rod 5 towards the interface of the connector body 1. The top of the threaded sleeve 4 drives the drive box 8 to move synchronously through the bracket until the output shaft 10 inside the drive box 8 is aligned with the two sides of the interface of the connector body 1. The micro motor 11 on the inner wall of the drive box 8 then starts. The drive wheel 12 at its output end is driven by the belt 13 to drive the driven wheel 14 to rotate synchronously. The output shaft 10 fixed on the inner surface of the driven wheel 14 rotates with the driven wheel 14, driving the protective plates 9 at both ends to rotate and close in the middle until the two protective plates 9 completely cover the interface area of ​​the connector body 1, forming a sealed protection to prevent external moisture and dust from entering.
